Genes affected

CHD1 (HGNC:1915): (chromodomain helicase DNA binding protein 1) The CHD family of proteins is characterized by the presence of chromo (chromatin organization modifier) domains and SNF2-related helicase/ATPase domains. CHD genes alter gene expression possibly by modification of chromatin structure thus altering access of the transcriptional apparatus to its chromosomal DNA template. [provided by RefSeq, Jul 2008]

The c.4931G>A (p.R1644Q) alteration is located in exon 35 (coding exon 35) of the CHD1 gene. This alteration results from a G to A substitution at nucleotide position 4931, causing the arginine (R) at amino acid position 1644 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
